WebNow that we have estimated the transformation from the T1 image, we can take that deformation and apply it to the fMRI data using spm12_normalize_write. Again, we are registering to the MNI template and will use a standard bounding box. We pass the anatomical, mean fMRI, and 4D fMRI data in to be transformed. WebSPM12 is software written in Matlab. It's one of the most popular packages for analyzing neuroimaging data (the top 3 are SPM, FSL, and AFNI), and the developers at UCL have made it free for everyone to use. You can do most everything in two ways: By clicking buttons in the graphic interface (GUI), and by coding. johnsons baby powder msds
